将bind:input 换成 bind:change 事件 去掉value绑定值

在这里插入代码片

<van-popup show="{{ showFinishTime }}" bind:close="onCancelFinishTime" round position="bottom" custom-style="height: 50%;">

  <van-datetime-picker type="datetime" min-date="{{ minDate }}"  bind:change="onInputFinishTime" bind:cancel="onCancelFinishTime" bind:confirm="onConfirmFinishTime" />

</van-popup>

``  onInputFinishTime(event) {

      const time = event.detail.getValues()

      const times = time[0] + '-' + time[1] + '-' + time[2] + " " + time[3] + ":" + time[4]

      this.setData({

        currentDate: times

      })

    },

-------------------------------------------------

亲测：去掉value绑定值，用bind:input也没事

 onInput(event) {

    if(event.detail){  

      this.setData({

        currentDate: event.detail

      });

    }

  },
